In this chapter, you will learn to measure land use change over time. Download and compare Synthetic Aperture Radar (SAR) satellite images of the Amazon rainforest in Brazil for 1994, 1995, and 1996.
Then use ImageJ, a public domain image analysis program, to identify forested and deforested land. Next, you will measure and compare the amounts of each. As a final product, you will create and interpret a color-coded image showing the oldest to most recently deforested areas for the three-year period.
